The invention reasonably utilizes a spatial structure in an engine compartment to cleverly design the positions and installation modes of the motor shell, the motor water channel, the water inlet and the water outlet, the cooling structure is simple and convenient to install, and the heat generated by the motor is taken away under the action of a cooling water pump and the radiator so as to achieve the purposes of rapid cooling and heat dissipation.
Description
Technical field
The invention belongs to the automobile drive electric motor technical field, heat radiation, be specifically related to a kind of pure electric automobile drive motors with radiator structure.
Background technology
The drive motors of pure electric automobile is positioned at enging cabin, when moving when the motor long-play or under the operating mode bigger to power demand of motors, the heating of motor is higher, for guaranteeing motor energy operate as normal, needs good radiator structure motor is dispelled the heat.
In the existing pure electric automobile drive motors system, adopt the wind-cooling heat dissipating mode mostly, its heat-sinking capability is lower.And the employing water cooling method that has, the mode of its channel structure, water nozzle mounting arrangements is unreasonable, and the heat that drive motors is produced distributes to come out, and motor temperature raises, and causes the frequent overheat protector of motor, even burns motor.
Along with the development of pure electric automobile technology, the heat-sinking capability that is arranged in the motor in the enging cabin is had higher requirement.Simultaneously, because the limitation in enging cabin space, need that radiating effect is good, compact conformation, motor easy for installation.
Summary of the invention
The problem to be solved in the present invention is, overcomes the problem of existing pure electric automobile drive motors heat-sinking capability difference, provides a kind of car of good heat dissipation effect to have the pure electric automobile drive motors of radiator structure.
For achieving the above object, the present invention adopts following technical scheme:
A kind of pure electric automobile drive motors with radiator structure, described electric motor of automobile adopt the liquid cooling mode to cool off.It comprises motor body and radiator structure.
Described radiator structure comprises motor housing body, cooling water channel and the nozzle and spout of radiation tooth, band sealed water jacket; Described radiation tooth is distributed in the surface of motor housing body; Be pressed with the water jacket that seals in motor housing body inboard; Cooling water channel is a spirality, is distributed in the inner housing surface of motor, is sealed by the water jacket of motor housing body inboard; Detachable nozzle and spout be installed in be communicated with cooling water channel respectively on the motor housing body as motor water inlet and delivery port; At described water inlet serial connection electric machine controller, delivery port is connected in series a radiator in addition, constitutes the path of liquid cooling circulation.
Described detachable nozzle and spout is 90 ° of distributions mutually on the motor housing body.
The invention has the advantages that:
(1) motor housing adopts the radiation tooth design, increases the surface area of housing, under the situation that cooling water channel is not opened, by natural air cooled heat radiation, improves heat-sinking capability; Under the situation that cooling water channel is opened, the existing liquid cooling heat sinking function of this motor has natural air cooled heat radiation dual-use function again.
(2) in motor, adopt the spirality cooling water channel, compare with the water channel that inside is complete empty, be beneficial to cooling fluid and circulate fully and dispel the heat, the situation of avoiding a part of cooling fluid can not circulate fully in the motor water channel takes place, make motor radiating abundant, the motor internal temperature gradient is little.
(3) the motor water nozzle can be dismantled, if water nozzle damages, does not need the entire heat dissipation housing is changed, and only needs that water nozzle is removed replacing and gets final product, and easy accessibility increases the service life.
This invention rationally utilizes the ingenious design electric machine casing of space structure, motor water channel, intake-outlet position and mounting means in the enging cabin, its cooling structure is installed simple and convenient, the very fast heat that motor is produced of effect by cooling water pump and radiator is taken away, to reach the purpose of quick cooling heat dissipation.
Description of drawings

The spiral channel outline drawing of Fig. 2, liquid-cooled motor of the present invention (this figure removes after the shell of band sealed water jacket);
The water nozzle profile enlarged drawing that Fig. 3, the present invention adopt.
Embodiment
The present invention is further described below in conjunction with accompanying drawing.
Referring to Fig. 1, outside motor housing body 2, be distributed with radiation tooth 1, for increasing surface area, improve heat-sinking capability, radiation tooth 1 is rectangular shape (certainly in addition, also can take other shape).Motor housing body 2 installed inside have sealed water jacket, and water jacket is an elastomeric material, during installation and motor housing body 2 be made of one and directly be pressed in above the water channel 3, seal.
Referring to Fig. 2, motor internal water channel 3 is spiral-shaped, is arranged in motor inner housing surface.
Referring to Fig. 3, the structure of dismountable nozzle and spout 4 is seen shown in the figure.In conjunction with Fig. 1 as seen, nozzle and spout 4 is 90 ° of distributions, install with motor housing body 2 and connect with water channel 3, as motor water inlet and delivery port, water inlet serial connection electric machine controller, delivery port is connected in series a radiator in addition, constitutes the path of liquid cooling circulation.
This motor is connected with mounting bracket with speed changer by fastening bolt.
